In the title compound, C18H18Cl2N2O6S2, the contains half a molecule with a center of symmetry at the mid-point of the central C—C bond. The dihedral angle between the benzene ring and the SO2—NH—C(O) segment in the two halves of the molecule is 83.5 (2)°. In the crystal, N—H⋯O(S) intermolecular hydrogen bonds link the molecules into infinite chains running along the c axis. The O atom involved in the hydrogen bond has a longer S—O bond than the other O atom bonded to S [1.403 (4) versus 1.361 (4) Å].

N,N-Bis(4-chlorophenylsulfonyl)-adipamide was prepared by refluxing a mixture of adipic acid (0.01 mol) with 4-chlorobenzenesulfonamide (0.02 mol) and POCl3 for 1 hr on a water bath. The reaction mixture was allowed to cool and added ether to it. The solid product obtained was filtered, washed thoroughly with ether and hot ethanol. The compound was recrystallized to the constant melting point and was characterized by its infrared and NMR spectra.
Needle like colorless single crystals used in the X-ray diffraction studies were grown by a slow evaporation of a solution of the compound in ethanol at room temperature.
The H atom of the NH group was located in a difference map and later restrained to N—H = 0.86 (2) %A. The other H atoms were positioned with idealized geometry using a riding model with the aromatic C—H = 0.93Å and the methylene C—H = 0.97 Å. All H atoms were refined with isotropic displacement parameters (set to 1.2 times of the Ueq of the parent atom).
The distance C1—C6 in the benzene ring was restrained to 1.39 (1) Å.

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes. |
Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger. |

The amide moiety is an important constituent of many biologically significant compounds. As part of our studies on the effects of ring and side chain substitutions on the structures of N-(aryl)-amides (Bhat & Gowda, 2000; Gowda et al., 2000, 2007), N-(arylsulfonyl)-amides (Rodrigues et al., 2011a,b) and N-(aryl)-arylsulfonamides (Gowda et al., 2005), the crystal structure of N,N-bis(4-chlorophenylsulfonyl)- adipamide has been determined (I) (Fig. 1).
In the two C—SO2—NH—CO—CH2—CH2 central segments of the structure, the N—H, C=O and C—H bonds are anti to the adjacent bonds, similar to that observed in N,N- bis(2-chlorophenylsulfonyl)-adipamide (II) (Rodrigues et al., 2011a) and N,N-bis(4-chlorophenylsulfonyl)-suberamide (III) (Rodrigues et al., 2011b). The orientations of sulfonamide groups with respect to the attached phenyl rings are given by the torsion angles of C2—C1—S1—N1 = -117.1 (6)° and C6—C1—S1—N1 = 60.5 (6)°. The molecule is bent at the S atom with the C1—S1—N1—C7 torsion angle of 55.0 (6)°, compared to the value of -65.1 (6)° in (II).
The dihedral angle between the benzene ring and the SO2—NH—C(O) segment in the two halves of the molecule is 83.5 (2)°, compared to the values of 89.6 (2)° in (II) and 79.5 (2)° in (III).
N—H···O2(S) H-bond formation results in an S=O2 bond longer than the S=O1 bond [1.403 (4)Å versus 1.361 (4) Å]. A series of N—H···O(S) intermolecular hydrogen bonds (Table 1) link the molecules into infinite chains running along c-axis (Fig. 2). The hydrogen bonding preferences of sulfonamides is described elsewhere (Adsmond & Grant, 2001)
